Description

Background

X.Org is an implementation of the X Window System. The X.Org X11 library provides the X11 protocol library files.

Description

Multiple integer overflows have been reported in the XGetPixel() function of the X.Org X11 library.

Impact

By enticing a user to open a specially crafted image, an attacker could cause a Denial of Service or an integer overflow, potentially resulting in the execution of arbitrary code with root privileges.

Workaround

There is no known workaround at this time.

Resolution

All X.Org X11 library users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=x11-libs/libX11-1.0.3-r2"
